A206.0 (A12060) Cast Aluminum
A206.0 aluminum is an aluminum alloy formulated for casting. A206.0 is the Aluminum Association (AA) designation for this material. A12060 is the UNS number. It can have a moderately high tensile strength among the ANSI/AA cast aluminums in the database.
The properties of A206.0 aluminum include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare A206.0 aluminum to: ANSI/AA cast aluminums (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition
Among cast aluminum alloys, the composition of A206.0 aluminum is notable for containing a comparatively high amount of copper (Cu). Copper is used to improve strength. This comes at the cost of a decrease in corrosion resistance and weldability.
